Remote Disconnect Features
The Remote Connect/Disconnect (RCDC) feature provides the means to
disconnect the load side terminals from the line side terminals by activating a
switch that is controlled by the meter. This can be used for applications such as
Pre-Payment Metering (PPM), Emergency Conservation Periods (ECP), Demand
Limiting Periods (DLP), and Outage Management. The RCDC feature provides
the means to connect or disconnect service with direct switch commands. Presence
of load side voltage will be detected, and service will not be reconnected (the
RCDC switch will not be closed) while load side voltage is present.
The load control modes and direct switch commands share control of the RCDC
switch. The RCDC function can be in one of the following states (listed from
highest to lowest priority):
• Locked open,
• Locked closed,
• Armed for manual closure,
• Opened and held open,
• Open due to outage management,
• Open due to load control service disconnect,
• Closed with service connected.
If the meter detects load-side voltage, the actual switch state will remain open until
load side voltage is no longer detected.
The softswitches associated with the RCDC feature, which provide additional load
limiting features, are reference in
Softswitches
on page 25.
Outage Management and Restoration
The outage management function enables meter to open the closed switch in an
event of outage. Note that the meter does not enter into outage open mode, if the
switch was already open, before the outage occurred. The meter can be
programmed to reconnect the switch, after restoration of power.
Enabling Outage Management and Restoration in I-210+
The meter supports two programmable options to restore the connection by turning
the switch on:
• Immediately after the power is restored.
• Wait for a predefined time before turning the switch on.
